The aim of this study was to collect taxonomical information for classification by using a scanning electron microscope (SEM) to examine the micromorphological characteristics of the species Acanthlimon, a member of the Plumbaginaceae family.For this objective the external floral micromorphology of the calyx, calyx tube, and bracts of 61 Acantholimon species from Turkey was investigated using a scan electron microscope (SEM), and we additionally performed cluster analysis.32 morphological features from 61 species of herbarium specimens were assessed in order to create a data matrix. Software called Multi Variate Statistical Package (MVSP) was used to analyze the data matrix. Phenograms were created using the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) analysis. Calyxes, bracts, and hairs were among the micromorphological characteristics oof Acantholimon that were studied in the study. The data were categorized into three groups based on qualitative and quantitative traits: trichomes, stomata, and surface sculpuring patterns. Trichomes were discovered on the outer bract, an uncommon Acantholimon trait. The remaining species have stomata on the calyx tube and bract, whereas only 2 species of A. Tragacanthinum and A. quinquelobum have stomata on the calyx. Six surface sculpting patterns were also discovered by the study: the Bract cell surface pattern, the sinuate pattern, the sinuate-reticulate pattern, the reticulate pattern, and the sinuate-sulcate pattern. The investigation in the phenogram revealed clusters. However, few species from other sections are not in close proximity to one another. Hence, to a certain extent, micromorphological characteristics are beneficial for identification.
